There is a lot of search volume in the supplement industry. There is also a range of keywords that should give some ideas as to content formats or ways to monetize your site.

“Optimum Nutrition” is the world’s best-selling whey protein. There are a number of keywords in this list related to protein, protein shakes, etc. That is probably because protein is the most common supplement gym-goers use to gain muscle.

You can also see a lot of people looking for information. Keywords like “calories in an egg”, “protein farts” or “is protein powder bad for you” have a pretty high search volume but not much competition at all. Focusing on these keywords is a great way to get traffic to your site through organic search.

However, there is no point in traffic for the sake of traffic. Luckily, there are a number of best “x for y” style keywords. Keywords such as “best fat burner for men” or “best diet pills for women” are perfect to target. The upside of these keywords is that they can be monetized through Amazon.

“DIY protein bars” also suggest that there could be a market for recipes for gym snacks.

These keywords highlight that there is:

  • A lot of search volume
  • Monetizable keywords
  • Keywords without too much competition
  • Lots of different sub-niches that can be capitalized upon

Who is Doing it Well?

1. Eat This, Not That!

Eat This, Not That!

Eat This, Not That! is a site that focuses on food, diet, fitness and health. This is a perfect site to promote supplements without being an outright supplement website.

They promote supplements through their shopping guides and monetize through Amazon.

Eat This, Not That!

Guides like this review of “The Best and Worst Protein Powders” are really simple. Eat This, Not That! takes them to the next level by breaking them down into the best animal based and plant based proteins to cater to a wider audience.

However, they also tell readers the worst protein powders. For a lot of people, price can be a driving factor. The site does a great job here of persuading their readers not to just buy the cheapest product. In doing so, they can increase conversions on the products that they are promoting.

Eat This, Not That!

The promotion on the site is not over the top. In fact, being more aggressive with the use of images and buttons (as long as they do not violate Amazon’s terms of service) might increase conversions.

2. Top 10 Supps

Top 10 Supps is an example of a very basic, but a very successful, supplement website.

According to Ahrefs, the site is getting around 198,000 visitors per month from organic search.

The reviews are very simple and, for the most part, all follow the same format.

What Deals are there in Supplement Affiliate Marketing?

Amazon Associates

Supplement offers Amazon Associates

The Amazon affiliate program is the easiest way to monetize the supplements niche.

It is relatively simple to get approval. It does, however, have very strict terms and conditions that must be adhered to. It is very easy to find yourself banned despite having no idea what you have done wrong. only offer a 1-day cookie but they do offer 15% commission for new customers and 5% for returning customers.

As the name suggests, the site offers supplements for bodybuilders or people simply interested in building muscle mass.



GNC is very similar to regarding what they sell.

They offer a 45-day cookie and, with that, you can earn up to 12% of the total value of the sale.

Pros of Supplement Affiliate Marketing

  • Lots of Offers: There are no shortages of ways to monetize your site
  • Opportunity to Grow: Once you become profitable with affiliate marketing, there is plenty of space to grow the site through other revenue stream (such as selling physical or info products)
  • Large Market: Lots of people buy supplements and the market is predicted to grow over the next few years
  • Not Too Competitive: There are a lot of supplement sites but this isn’t necessarily a bad thing. It means that there are not 1 or 2 sites out there hoovering up the majority of traffic.

Cons of Supplement Affiliate Marketing

  • Large Market: Lots of people buy supplements and the market is predicted to grow over the next few years
  • Disreputable Companies: There are a lot of offers that you should be careful with. Your reputation is tied to the products you recommend. Make sure the company delivers what you have promised.

Should I Start a Supplement Affiliate Marketing Website


There is definitely still space for more websites in the supplement space.

There is a lot of search volume, SERPs are not prohibitively competitive and there are enough sub-niches and categories to find an interesting angle that will allow you to form a community further down the line.

There is also scope to promote supplements from within other niches. For example, you may run a vegetarian lifestyle blog. You may want to promote zinc supplements on your site because many vegetarians suffer from a shortage of zinc in their diet.

It is easy to monetize the site on Amazon, Clickbank or through countless other ways.

The supplement niche also leaves room to grow into a site that sells info products, or even physical products, in the future.

  1. Amazon is not good affiliate in long run, they gave you few % of every sale you made, worth it? NO. Better to find local ecommerce sites and tell them that you want 8 – 15% per sale. Both is win-win , as amazon is getting more and more capitalistic you’ll also help smaller sites, get more.

    That makes me to earn more money, amazon affilaite is a long gone, not really worth it in my opinion.

    Also niches sites are really harder and harder to set up because of INSANE COMPETITION!

    1. I completely agree that it’s better to find more profitable programs eventually. However, there are two problems with this approach.

      One is that it takes a lot of time and effort to find, test, negotiate and set up individual deals with other programs. It’s only worthwhile when you are already making some money, otherwise, you spend a lot of effort improving the profitability of articles that don’t make any money.

      Second, it’s a lot more complicated for beginners to take this approach.

      The best way is to start with Amazon. Grow your site and focus on your core competencies (content + links usually). Once you reach a point that it makes sense, then you can start working on testing different offers/programs.

  2. The problem is how to write high quality content and independent reviews about specific health and fitness topics and products, that needs a lot of time and efforts and not anyone can promote health supplements or start a health website. for that we see low competitive niches related to dietary supplements.
    And about commissions, I don’t prefer using Amazon because of its low commission structure, you can find other websites that offer at least %10 in commissions.

  3. Hey! one of the issues I always had with a health niche blog is the commission rates, obviously, Amazon is the easiest platform because of the big weight the brand holds but the commissions are very low, around 5% to be exact. while other offers on Maxbounty and other affiliate networks offer a set price for the same item. for example, selling a CLA weight loss supplement. on Amazon, an average commission would be around 3$ while on other affiliate sites its 35$ but come off as spammy with the squeeze page that is provided. what is your take on this? should I go with the trusted Amazon brand or go after the higher commission rates on Maxbounty but could potentially come off as spammy?

    1. Great question Javan! We’ve struggled with this too as we hate these spammy offers. To be honest, we don’t have a solution for it yet. I know there are good quality products with good affiliate offers out there, we just haven’t taken the time to find them and promote them. It’s absolutely on our radar and something we’ll look at soon.
